To @ZZ zowm, it 12a-Cty concern:

Be it known that I, CHARLES J. ADDY, of Malden, county of Middlesex, audState of Massachusetts, haveinvented an Improvement inBurnishingirlachines, of which the following description, in connectionwith theaccoinpanyiug drawings, is a specification, like letters on thedrawings representing like parts.

rlhis invention in machines for bnrnishing boot and shoeheels is animprovement upon the machine shown and described in United States PatentNo. 127,414, dated June el, 187,2. In the machine described in the saidpatent the shoe is oscillated and the burnishing-tool is moved acrossthe heelsedge by hand.

My invention has for its object to automatically operate theburnishing-tool; and my invention consists, essentially, of mechanism,as will be described, to cause the burnishiug-tool to move transverselyor horizontally on the heel-edge to polish the same, the said mechanismbeing made adjustable, so that the bnrnishing-tool may be made to bearupon and polish uniformly heel-edges of varying sizes and shapes.

Figure 1 is a side elevation of aburnishing machine constructed inaccordance with my invention, one of the standards being broken off atits upper end; and Fig. 2, a section of Fig. 1 on the line x oJ-,lookingtoward the left.

The base A, provided, as shown, with two standards or pedestals, A A, tosupport suitable bearings, o', for the rockershaft c2, and the carriageor jack c, attached to one end of the said rocker-shaft to carry theboot or shoe, are substantially as shown and described in the patentreferred to, the said shaft being rocked or rotated by means of atoothed sector, (LX, mounted upon thestudl2 and engaging the pinion a onthe rockshaft, the said toothed sector being connected by the link c5 tothe crank-pin c (see Fig. 2) oi the crank or disk el, fast on the mainshaft B, the latter being supported in suitable bearings, I), andprovided. with drivingpnlleys b', the said parts bei ng and operatingsubstantiallyr as shown and described in the said patent.

The standard A has pivoted toit at its top one end of a horizontal baror carrier, c', extended across the machine and entering between theprojected ends 2 of the standard A?.

The carrier c at its front end has pivoted to it, as at c, atool-carrier, If, provided, as shown, with a longitudinal opening,through which a rod, A5, is extended.

The rod 5, as shown, is reduced in diameter for a portion of its length,as at 6, which latter is extended up through a narrow portion of theopening referred to, and is provided with a pin, t6, extendedthroughslots bin the Sides of the tool-carrier b", only one of said slots beingshown in Fig. 1.

The rod 5 has secured to its lower end, as herein shown, by set-screw 7,the iron or other usual burnishing-tool, b", which in operation isnormally pressed against the heel bya spring, bl, the latter encircling`the narrow portion 6 of the rod 5, and having one end bearing againstthe upper wall ofthe opening' through which the rod 5 is extended, thelower end of said spring resting on the pin b5.

The bar or carrier ois recessed at its under side to receive a spring,c2, encircling` a post, c3, extended upward from the standard A2, thesaid spring normally acting to raise the carrier o. The tool-carrier li'is also pivoted at its upper end, as at d, to a lever, d', having itsfree end adjustable in a slotted arm of a lever, d2, pivoted at di' toan arm, d", the latter being attached, as herein shown, by screws d5, toan arm or bracket, t, secured to the upright A. 'The lever d2 at one endhas a stud, c, (see dotted lines, Fig. 1,) which enters a camgroove. e,in a disk, c2, attached to or forming part of a wornrgear, ci.

The worm-gear c and disk cZ are rotated by a worm, e5, on a shaft, e",having bearings in the arm or bracket al, the said shaft having mountedthereon pulleys f, connected by belt f2 to pulleyj3on the main shaft,there being a fast and slow pulley on each shaft, to produce a fast orslow movement of the mechanism operating" the burnishing-tool.

During the rotation of the worin-gear the lever d is turned on itspivot, the outer periphery of the cani-groove acting on the stud e, andas the said lever is turned on its pivot the tool-carrier b'i is rockedor moved forward and backward on the pivot o through the lever d', thebackward and forward movement of the tool-carrier causing the tool totravel laterally or substantially horizontally over the IOO heeledge ofthe boot or shoe held in the jack, as hereinshown, by the screw l0, thetread of the heel resting against `the pattern-plate 7L of the saidjack.

By adj ustiug` the free end of the lever din the slotted arm of thelever d by means of the setscrew 8, the stroke of the burnishing-tool blaterally over the heel-edge may be varied, so as to enable -heels ofvarious heights or sizes toV beburnished or polished uniformly andequally well.

In operation theboot orshoeisjacked and the burnishing-tool is broughtdown incontact with the heel-edge bythe operator pressing upon afoot-lever, h', fuloruuied to the base A and connected to the carrier cby rods 71,2, as in the patent referred to, the said foot-levcr havingerected upon it a shipper, if, to ship the belt from the loose tothefast belt-pulley as the carrier is depressed. The foot-lever ismaintained depressed and in operative position by means of a catch orstop, herein shown as a rod, 7.

The pivotal point d3 of the lever d2 and the slot in the said lever areall so constructed and shaped that in any adjustment the stroke of thetool-carrier and tool is such as to always come back to and stop at thepatternplate, against which the tread end of the heel rests, or, inother Words, the inward stroke of thetool b3 is always to the samepoint; .but its outward stroke may be varied more or lessby altering theposition of the set-screw 8 inthe slot of the lever d2.

1.l In a machine for burnishing heels of boots and shoes, the jack orcarriage and means to oscillate it, a burnishing-tool, a4 pivoted car-`rier therefor, a cani, `andnieans, substantially i cillate it, aburnishing-tool, a carrier `for it, a

lever, c, on Whiehlthe said carrier is pivoted,

an'd means, substantially as described, to depress the said lever toforce the tool against the heel/combinedwith the lever d" and with a 11second lever having one end secured to the pivl oted toolcarrier and itsother end adjustable on the llever d2, toopcrate substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

CHARLES J ,i ADDY.`
